A

A-Class Planet - a planet with a tenuous or absent surface and reducing (methane) atmosphere which radiates heat; a "failed star"
example: Jupiter in the Sol system

B

B-Class Planet - a planet with a tenuous surface and reducing atmosphere which is non-radiant
example: Neptune in the Sol system

C

C-Class Planet - a planet with an iron/silicate surface, dense reducing atmosphere, and a high surface temperature
example: Venus in the Sol System

D

D-Class Planet - a planet with a nickel-iron/silicate surface (subclass A-G have no atmosphere, H-N tenuous atmosphere); [large] asteroids
example: Ceres

E

E-Class Planet - a planet with a silicate surface and some metals, the atmosphere can be reducing or oxidizing and it has a large molten core
example: Janus VI

F

F-Class Planet - a planet with a silicate surface and some metals and an oxidizing atmosphere, it is a very young planet
example: Delta-Vega

G

G-Class Planet - a planet with a silicate surface and a thin oxidizing atmosphere; a desert planet
example: Rigel XII

H

H-Class Planet - a planet with a silicate surface and variable atmosphere which is geologically active
example: Gothos

I

I-Class Planet - a planet with a metallic/silicate surface and fluid(very dense) atmosphere; a small, young planet
example: Excalbia

J

J-Class Planet - a planet with a silicate surface and very tenuous atmosphere comprised primarily of noble gases; moons
example: Luna(Earth's Moon) in the Sol system

K

K-Class Planet - a planet with a silicate surface and tenuous atmosphere, they may have water and be adaptable with pressure domes
example: Mars in the Sol system

L

L-Class Planet - a planet with a silicate and liquid water surface with an oxidizing atmosphere which is geologically inactive
example: Psi 2000

LaGrange Point - A point between any two astral bodies were the forces of two gravity wells interlap. The overlapping area is in constant flux but still relatively stable. Theoretically it would be possible to hold anything from a satellite to a small space station in place. The energy radiating from both stars would be enough to hide whatever was located at that stable position from sensors.

  • The USS Heracles found a pirate base in a LaGrange Point in the Jalco System of the Portal Sector. They launched two probes, but both were unable to overcome the gravitational forces to transmit any useful data. The base was successfully destroyed on SD:08.0410 by the USS Heracles.

M

M-Class Planet - a planet with a silicate and liquid water surface with an oxidizing atmosphere which is geologically active
example: Terra(Earth) in the Sol system

N

N-Class Planet - a planet with a surface entirely covered with liquid water(pelagic) with an oxidizing atmosphere
example: Argo

R

Roche Limit - The limit at which gravitational forces that hold an orbiting body overcome the inherit tensile strength of the body and it is pulled apart.

  • The USS Demora-Sulu documented a planet approaching its Roche Limit, but was called away on a distress call before the phenomenon could be observed. The USS Olympus-Mons observed and was caught in the shock wave of the planet when it finally reached its Roche Limit slightly earlier than predicted.
